Although the 2014 Met Gala Monday night in New York City was packed with A-listers, clearly, one star stole the show -- Lupita Nyong'o, who had jaws dropping in a green Prada creation and a matching bedazzled headband.
ET correspondent Nigel Barker caught up with the Oscar winning actress on the red carpet, where she explained how her outfit choice came about, and how it was directly inspired by the theme of the night -- a tribute to twentieth-century designer Charles James, who's often referred to as America's first couturier.
"Well you know, this is actually the first sketch that Prada showed us. And we nixed it, and then they made it anyway," she revealed. "When we saw it, we really didn't understand it in a sketch, but it made so much sense when it was made, and I call it the taxi dress. [It was made after Charles James] who made dresses women could slip in and out of."
Another A-lister very familiar with taking red carpet risks?
Co-chair of this year's gala Sarah Jessica Parker, who explained that it was actually her idea to put the name of the designer of her gown -- the legendary Oscar de la Renta -- on the back of the train.
"This was especially meaningful to me because I was co-chairing with Mr. Oscar de la Renta, and I very much wanted him to build the dress, and he agreed, so putting his name on the back was my idea. He would never-ever have allowed for that, but I forced him," she smiled. "I forced him to let me do that because I thought, we've had a really long relationship and I admire him so, and I think he's one of the most elegant men. So this is for him."
